My Timken book shows an F44hd option from 81-91 that used the #3 and #5 bearing. The #3 and 6 was light duty (I guess) all he seals are the same from 71-91. According to the RPO codes, the F44 is a heavy half where it took the GVW up another 500 or so pounds. I also think that option was a given if you got either a diesel engine or a big block?
